A more complete answer, as I was kinda hangry when I answered last
https://www.drupal.org/project/activitypub - the most wordpress like, and just like wordpress it's focused on being a complete site builder. Also like wordpress it's bloated (but it is less bloated than wordpress)
https://ghost.org/ - intentionally focused on blogs, newspaper style posts where there's not often layout changes, with themes & templates for posts just like how wordpress does. Simple by design, but less simple than the next 2, also more flexible than the next 2
https://writefreely.org/ - text focused, even simpler by design, basically only really one page layout option
https://joinplu.me/ - text focused, but can fully customise the CSS, though not as many layout options
